How to install the j2-based Development Environment

To perform the development of J2EE, you must first establish a development platform. There are four solutions for the development platform selection.
1. Borland Jbuilder platform with comprehensive functions (recommended)
To build this platform, we must install: JBUILDER 7, JBUILDER 8, JBUILDER 9, borland mobileset 3.1. Optional materials: (Note that these are not necessary and you can develop without them) the mobile phone SDK you want to develop. For example, to develop on NOKIA, you must prepare the nokia developer's SUITE, you can also add some simulators, such as 7210, as needed.
With the above materials, we can build a very good development platform.
Procedure:
(1): Install and register JBUILDER. (If JBuilder 9.0 is installed and fully installed, skip to Step 3 without installing MobileSet 3.1)
Note: The JBuilder installation directory name cannot contain spaces (for example, it cannot be installed in the Program Files directory because there are spaces in the middle). It is best to install it in the default directory. JBuilder will not cause space issues. When MOBILESET 3.1 is installed in the next step, it will end with space issues.
(2): Install JBUILDER correctly. After successful registration, install MOBILESET 3.1. After installation is complete, you need to register. MOBILESET is free of charge. You can ask BORLAND for a registration code, you can also use the registration code in Appendix 2.
Note: MOBILESET 3.1 is installed in a custom mode. The second item (feature guard Obfuscator) is not selected during installation.
(3): After completing the steps required in the preceding two steps, you can install the DEVELOPER's SUITE and simulator you selected. (For how to install the nokia sdk, see Appendix 1 ).
(4): After completing the preceding steps correctly, it can be said that the platform has been built, which is so simple. What you need to do below is to create a new project in JBUILDER, in the displayed form, JDK selects the j2_type, and all others use the default one. After completing the configuration, select NEW. At this time, the two options on the MIDP page should be optional, now you can develop it.
2. Use Sun's official tool and the Wireless Development Platform j2me_wireless_toolkit
To build this platform, we must install the following materials: jdk1.4, j2me_wireless_toolkit1.04, or j2me_wireless_toolkit2.0: (Note that these are not necessary and you can develop them without them) the mobile phone SDK you want to develop, for example, you must prepare the nokia developer's SUITE for development on NOKIA. You can also add some simulators such as 7210 as needed. (For the installation method of the nokia sdk, see Appendix 1 ).
With the above materials, we can build our current platform.
(1): Install jdk1.4 first. (In method 1, because JBUILDER comes with JDK, you do not need to install JDK separately .)
(2): After JDK is correctly installed, j2me_wireless_toolkit can be installed, regardless of 1.04 or 2.0. Both can be installed.
